Today I was on a flight from Copenhagen Kastrup (EKCH) to Oslo Gardemoen (ENGM).Approaching Oslo, I was instructed to land at runway 19L. ATC navigated me towards the ILS, and I responded promptly every time ATC asked me to either descend or turn.Then suddenly I get this: "Scandinavian 737 , IFR flight plan is cancelled, radar service terminated. Squawk 1200. Maintain VFR. Frequency change approved."The built-in ATC still sucks big time.I was ping-pong'ed between Malmoe and Oslo Center 12 times without getting any messages from either of them.I still experience AI aircraft getting permission to land or take off while I am still at the same active runway.I often hear this, for both AI aircraft and myself: "You are 0 above your assigned altitude..."And AAARRRGGGHHH... (Taking out the keyboard and smashing it to the side of the computer)ATC got worse than in FS2002, and IMHO it is taking out much of the joy of those things, which are improved after all.Just some ######in'...Nico

Try reducing your AI to 0% and see whether the same thing happens. It could be that there's a lot of traffic and ATC felt you didn't respond fast enough.
